Mining Concentration Factor

Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit.It may begin as soon as the pre-development steps are complete.Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.

We are a large-scale joint-stock enterprise integrating scientific research, production and sales.Our leading products have crushing equipment, sand making equipment, mobile crusher, etc., Each type of product is with complete specifications. All products have passed ISO9001, CE and GOST international quality system certification.
